Print when a toner cartridge is at estimated end of
life

Black cartridge is low: The product indicates when a toner cartridge level is low. Actual toner

cartridge life remaining may vary. Consider having a replacement available to install when print

quality is no longer acceptable. The toner cartridge does not need to be replaced now.

Black cartridge is very low: The product indicates when the toner cartridge level is very low.

Actual toner cartridge life remaining may vary. Consider having a replacement available to install

when print quality is no longer acceptable. The toner cartridge does not need to be replaced now

unless the print quality is no longer acceptable.

Once an HP toner cartridge has reached “very low”, HP’s Premium Protection Warranty on that toner

cartridge has ended.

You can change the way the product reacts when supplies reach the Very Low state. You do not have

to re-establish these settings when you install a new toner cartridge.

Enable or disable the Very Low Setting

You can enable or disable the default settings at any time, and you do not have to re-enable them

when you install a new toner cartridge.

1.

From the Home screen on the product control panel, touch the Setup button.

2.

Open the following menus:

System Setup

Supply Settings

Black Cartridge

Very Low Setting

3.

Select one of the following options:

Select the

Continue

option to set the product to alert you that the toner cartridge is very low,

but to continue printing.

Select the

Stop

option to set the product to stop printing (including printing faxes) until you

replace the toner cartridge.

Select the

Prompt

option to set the product to stop printing (including printing faxes) and

prompt you to replace the toner cartridge. You can acknowledge the prompt and continue

printing. A customer configurable option on this product is "Prompt to Remind Me in 100

pages, 200 pages, 300 pages, 400 pages, or never." This option is provided as a customer

convenience and is not an indication these pages will have acceptable print quality.

When the product is set to the

Stop

option, there is some risk that faxes will not print after the new

cartridge is installed if your product has received more faxes than the memory can hold while stopped.
